/* ============================================================
   Sound Net web demo — Sound Genetics studio theme.

   Ported from mockup/studio-v2.html (the signed-off design), with the
   mockup's ad-hoc class names replaced by the production component names
   the ui-*.js modules emit.

   Type rule: the grotesk (--ui) carries every piece of UI text; --mono is
   used only for numerals — timestamps, confidences, the ms readout, the
   session clock, the timeline axis.

   Fonts are loaded by index.html (Inter + Roboto Mono); the token stacks
   below fall back to system faces if that link is absent.
